I used DAP Weldwood brush on contact adhesive, the same type used for installation of formica tops, also available at Lowes or Home Depot and it does not harm the foam.

You brush an even layer on both surfaces, allow a few minutes for it to tack, then press the 2 surfaces together but be sure it is exactly where you want it, there is no re-positioning, once the 2 surfaces touch it is going to stay there.

The contact adhesive will also bond the edges of the foam, but I used the black foam rubber pipe insulation with the peel off edges with preapplied adhesive underneath, that helped being able to create larger sheets simply by bonding together multiple cuts.

I basically cut triangle pieces to cover the PVC end caps, that worked really well, then used adhesive backed Aluminum duct sealer tape to cover the entire thing.

The 1/2" thick foam gave me about twice the insulation layer than what I previously had.

Haven't tested it's insulative value yet vs what I had, but I'm really close to getting my setup back in business, all that's left is the input output tubing, and soldering all the connections.

so, do think that getting the pipe insulation, and cutting it to fit, would be cheaper way for me to go?
I want to go 2" 's thick with the insulation on the reservoirs, so, that would be four layers of the pipe insulation.
that is also why I was looking at getting 4 half sheets of the neoprene, so, that I could go 2" 's thick with it.

It may be easier to build up your thickness bonding layers together and overlapping the seams than to wrap a 2" solid layer.

One caution:

If you use the contact cement take it outside in the fresh open air, the fumes will have you high as a kite inside the home.

ok, so I will go take a look and see what they have for pipe insulation.

ok, so after fitting the 40mm TEC's to the 50mm CPU blocks, I am really liking how they look with the larger base on the smaller TEC. all I have now are the hot side CPU blocks but they are the same size as the all metal cold side blocks I ordered. I really wish that they made some 60mm CPU blocks, that I could use for 50mm TEC's, but that is what upgrades are for. I will most likely order some of fox's 62mm blocks as upgrade water blocks for the main TEC assembly at some point. I really like how fox's water blocks look, as well I would like to ask him if I could have three of his water blocks special made, with copper tops for the cold side of the TEC's on the main TEC assembly.

You can look into Bykski CPU-XPR-A CPU block, it is 85mm x 85mm x 6mm, usable surface is about 60mm x 60mm. Only things I think it is bad for TEC is like all modem CPU block are center concentrated cooling and it is expensive, cheapest I found on E-bay is $70. (vs Taobao's $36 )

The problem with that water block is the useable internal cooling area is a lot smaller than the overall size of the water block.

yea, I looked at them, Fox's water blocks are a really nice design, I will have to save up for that upgrade, but I think those water blocks will be worth it.

The perfect CPU water block for a 50mm x 50mm peltier is the Swiftech Apogee XT or XTL, but it has to be flow modified because it is a center injection block, but good luck finding any of them anywhere.

It can actually be modified to pickup the cold produced by the entire size of the 50 x 50 peltier and after removing the center injection is a perfect cold pickup water block.

For a 40 x 40 a flow modified XSPC RASA will work but good luck finding any of them anymore as well.

I am running 3 of the Swiftechs and tried to find a backup block but couldn't find one anywhere.

The problem with the channel style water blocks is the copper or aluminum contact surface is too thick, and a channel flow water block is actually designed to cool the hot side, not pick up cold to store in the insulated reservoir.

The requirement for the perfect cold pickup water block is the thinnest layer of metal between the cold side of the peltier and the coolant, high flow rate with almost zero restriction, and the cavity inside the water block large enough to cover the entire peltier size.

For cold storage you need to remove the cold the peltier produces as fast as possible and do not let the cold build up in the water block itself, let the cold build up in the insulated reservoir.


What I have bolded above is exactly why my chilled water cooling actually works.

The good thing is that it is locally available at Lowes or Home Depot if you come up short just go back to the store no need to wait on an online order and pay shipping charges.
